How do you tell someone "bless you" in Spanish?
Bless you... as when someone sneezes... "salud"
Bless you... as in God bless you "que Dios te bendiga"
Bless your heart it's not commonly said in Spanish... unless it's being spoken in a religious context... "bendito sea tu corazón", and it probably would be addressed at Christ or some other religious figure...
my spanish teacher taught us that you say salud (wishing them health) the first time they sneeze and then if they sneeze again sometime shortly after, that it is custom to then wish them dinero (money - meaning wealth) after the second and amor (love) on the third. for example someone once sneezed three times in one class period and we had all said salud, dinero, then amor
